SHREDDING-HAMMER.

Specification of Letters Patent. Patented July 23, 1312 Applicationfiled October 29, 1910. Serial No. 589,800.

To all whom it may concern:

Be it known that I. )lIL'rox F. \YrLLiAns, a citizen of the UnitedStates. residing .at St. Louis. Missouri. have invented a certain newand useful Improvement in Shredding- Hammers, of which the following isa full. clear. and exact description. such as will enable others skilledin the art to which it appertains to make and use the same-referencebeing bad to the accompanying drawings, forming partof thisspecification, in whichi A 4 Figure 1 is a side elevational view of myimproved'hammer: F ig. 2 is a front elevational view of the same: Fig. 3is a modi-.

fied form; Fig. 4 illustrates a side and front elevation of a modifiedform.

This invention relates generally to shredding machines of the rotary'hammer type, and more particularly to hammers or beat- 7 ers forshredding machines, which hammers or heaters are provided at one endwith a series of prongs or tines, that bearcutting edges adapted. tocooperate with parts within the machine in which the hammers or heatersare used, for cutting and shreddingthe material delivered into themachine.

The present invention is designed partipularlv for use in shreddingcloth and other fibrous material which is fed into the machine overprojections, such as shown in Patent No. 953,111, granted to me March2'3.

.enters the material the tine makes a shearing cut to cut the material.

In the drawings, 1 indicates the shank of a hammer or beater which isprovided with an opening whereby it is pivotally mounted upon itssupport. This shank is given a quarter turn and has its outer end bentor curved as shown.

2 indicates a clamp held in position by rivets and having an overhangingportion for securing the cutting tines 3 in position. These tines, asshown in Figs. 1 and '2, extend effect a shearing cut. In' the eventthat material is, wedged into the tines, atlditional material crowdingdown upon it will effect a severance of the fibers and hence I prefer tohave the side cutting edges meet in a sharp angle as shown.

In Fig. 3 I have shown a reversible shredding blade 5 having tines onits front and rear edges and-being provided with a projection 6 which isreceived. in a groove in the outer end of the shank. A rivet 7 holds theparts together.

InFig. 4 the tines Sa re provided with means for connection with astraight shank 9.

In all of the above forms of my invention the comb-shaped beater has anumber 0f tines provided with'inclined cutting edges and sharp enteringpoints, the beater being renewable or reversible, as the case may be. inthe event of wear. v

The curved edge 1 of the supporting shank is preferably sharpened sothat in the event that fibrous material is crowded between the tinessaid sharpened edge will tend to sever it.

I claim:

1. In a device of the character described the combination of a shank. apart removably secured to said shank, said last named part having aplurality of forwardly and outwardly curved tines tapering from base topoint and triangular in cross section.

2. In a shredding hammer thecombination with a shank. of amemberdetachablv .appl1ed to one end of said shank. which inember comprises aserles of tines which are directed transversely of said shank, andthe-pr'O ectmg portions of which tines have medial and lateral cuttingedges and entering points.

The herein-described shredding hama mer comprising a shank and a memberhaving a series of tines detechably applied to one end of said shgmk,which tines gradually tai e1: toward their outer ends and are provide ontheir sides with cutting edges.

f 5 4. In-a. shredding tion'wit-h a shank, of a-t-ine detachablyepplied.to one end "of said shank, which tine hammer the combinatap'ers adual-ltoward its outer endand i .prov dedwit a pair Ofoppqsitely dis:
